3 Claimant The present invention relates generally to pipe connectors, and more particularly to a novel construction for effecting a tight non-obstructing seal for a pipe connector.

An object oi the present invention is to provide a pipe connector which includes a novel construction for effectively sealing the same and for maintaining a sealing means in place relative to its seat in disassembly of the connector. it Another ohject is to provide a pipe connector which is adapted to insure long life of the packing and in which the passageway for the fluid cannot become obstructed through the forcing oi portions oi the packing thereinto.

Another ohjectis to provide a pipe connector which includes telescoping elements for the passage of fluid lrom one pipe to a second pipe.

Another object is to provide a pipe connector which includes telescoping elements and a sealing construction :ior preventing leakage.

Another object is to provide a pipe connector which is sturdy and compact in construction and which is adapted to fulfill its functions over a long period of time. I Another object is to provide a pipe connector including means to maintain a packing member in place when the connector is taken apart.

Other objects and advantages will be apparent from the following description, taken in conjunction with the accompanying drawing, in which:

Fig. l is a side view of a pipe connector constructed in accordance with the teachings oi the present invention;

Fig. 2 is an end view of the pipe connector shown in Fig. 1, looking in the direction of the arrow A;

Fig. 3 is a section on the line 33 of Fig. 2;

Fig. 4 is a view of the other end of the pipe connector shown in Fig. 1; and,

Fig. 5 is a sectional View taken on a diameter of a preferred packing member.

Referring to the drawing more particularly by reference numerals, there is disclosed a pipe connector H]. The pipe connector l0 includes a main telescoping member or body H, a secondary telescoping member l2, an assembly ring l3, and a packing member or sealing ring It.

The main telescoping member ll includes a right angularly bent pipe section l6 which terminates at one end in a pipe receiving enlargement I! having internally disposed spiral threads l8. Concentrically disposed about the other end- IQ of the pipe section I6 is an annular wall 20 which is connected to the pipe section 1 thy a conical flange 2|, thereby forming a circular trough. The wall 20 extends slightly beyond the extremity of the end it) and has external threads iii. An elongated projection 23 having spaced apertures ti therethrough extends outwardly from the wall 20. The flange it merges into the 5 wall oi the pipe section it at the juncture as a matter of convenience in construction, as can be appreciated from an inspection oi Figs. i and 3. The end Id of the pipe section it has an external peripheral groove 25 and is circumierentially W thickened at to to provide the conical surface ill.

The secondary telescoping member it is preferably oi the central cross section shown in Fig. 3, being in the form of an elongated irregular sleeve. The member ll! includes a pipe receiving section to which has internal spiral threads 3!]. A cylindrical section it is connected to the pipe re ceiving section 29 by an intermediate section till, the intermediate section 32 including an internal annular groove ill, a plane annular surface 33, 20 and a cylindrical surface it. The cylindrical section it terminates at its free end in right angularly intersecting cone surfaces 35 and 3B.

The assemloly ring i3 includes a cylindrical section ill and a ilange 3B. The cylindrical section. ill has internal threads 39 and spaced external hosses 3'1.

The packing member M is an annulus, preferably of resilient material, and is or the cross section and general configuration shown in Fig. ii. The member it includes two annular legs 40 and 4t connected by the annular portion 42. The annular legs 40 and 4! include, respectively, a conical surface 43 and a conical surface 44 which are adapted to rest against the internal conical surface of the flange 2! and the conical surface 35 of the secondary telescoping member l2, respectively, and the portion 42 has a cylindrical surface 45 which is adapted to engage the inner cy- 40 lindrical surface of the wall 2|]. The configuration of the packing member I! is such that it fits within the trough formed by the end IQ of the pipe section IS, the flange 2|, and the wall 20, and is adapted to be so held by the groove 25. 45

Pipe sections 50 and 5| are shown screwed into the enlargement l1 and the pipe receiving section 29, respectively.

The several elements comprising the pipe connector III are constructed of suitable material. 50

readily grasped by a. study of the drawing. The

packing member I4 is disposed between the wall 55 advantages sought therefor.

2| and the end I! of the pipe section it with the leg ll hooked in the groove 2!. The secondary telescoping member I! is telescoped relative to the main telescoping member II with the free extremity of the cylindrical section ll of the former engaging the packing member It. The

assembly ring I! is disposed about the secondary telescoping member I! and is threaded onto the wall III of the main telescoping member II with the flange is engaging the plane annular surface 33 until the packing member H is tightly compressed. The ring I! is locked in position by any type vof key inserted through one of the openings 24 and disposed between two of the bosses 31'.

When the pipe connector II is dismantled and the member I2 withdrawn from the member II the packing ll remains in place due to its configuration and the groove 2!. This is advantageous, since the likelihood of its loss, or the failure on the part of a worker to reinsert it, is thereby obviated in those instances where the connector I is dismantled for repair work other than th replacement per se of the packing ll.

When the packing member I4 is compressed and subjected to the heat of steam, or the like, passing through the connector II it assumes the cross section shown in Fig. 3, exhibiting an inherent characteristic of the material of which it is preferably constructed. The telescoping of the members II and I2 is highly advantageous. It is impossible to pinch'the packing I or to squeeze it into the passageway of the fluid. The instant construction, of course, results in a longer life for the packing II and a continued unobstructed passageway for the fluid.

It is, of course, tb be understood that where the pipe connector II is employed to operatively associate two already located pipes the members II and llare threadedly disposed upon the respective pipe sections before iina-l assembly. This; of course, involves only a matter of pipe connecting routine.

It is clear that the pipe connector II is of a construction to obtain all of the objects and v It is to be understood that the foregoing description and accomamass:

panying drawing have been given by way of illustration and example and not for purposes of limitation, the invention being limited only by the claims which follow.

What is claimed is:

1. A pipe connector comprising a first member having a circular trough, a second member extending into said trough and thereby telescopically engaging said first member, a packing member in said trough between the extremity of the second member and the bottom of the trough, means for maintaining said packing member in associated relationship with said first member, and means maintaining said member telescopically engaged and said packing member compressed to seal the joint between the said members.

A pipe connector comprising a flrstmember having a circular trough, a second member extending into said trough and thereby telescopically engaging said first member, an annular groove in the inner wall of said circular trough, a packing member in said trough between said second member and the bottom of the trough, said packing member including a portion extending into said groove to maintain it in position relative to said first member, and means maintaining said first and second members and said packing member in operative disposition.

3. A pipe connector comprising a flrst member having a circular trough, an annular groove in one wall of said trough, a packing member in said trough having a portion conformed to the bottom of the trough and to the groove and to a portion of the other wall, whereby the same is retained within said first member after installation, said packing member further having a portion spaced from the conformed portion and adapted to be compressed thereagainst, a second member having a circular portion extending into said trough and compressing said packing to seal the juncture. and means maintaining said second member in its sealing disposition relative to said first member and said packing member.
